PrimaLuna EVO 100 Tube DAC

Overview

The PrimaLuna EVO 100 Tube DAC brings the warmth and dimensionality of vacuum tubes to digital playback. Built around the acclaimed TI Burr Brown PCM1792A converter and PrimaLuna's SuperTube Clock, it delivers the resolution and detail retrieval you expect from a modern DAC while adding the organic texture that only a genuine tube analog stage can provide. This is not a single tube buffer bolted onto a chip design, it is a fully realized dual mono topology with per channel dedicated tubes.

Weighing nearly 29 pounds, the EVO 100 is built like the finest tube electronics. Dual potted toroidal power transformers, tube rectification, and the AC Offset Killer work together to lower noise to a level that lets the smallest musical details emerge from a deeply black background. Point to point wiring throughout the signal path keeps the connection between your source and your system pure and direct.

With USB, AES/EBU, coaxial, and optical inputs, the EVO 100 handles PCM from 16 bit to 24 bit and 44.1 kHz to 192 kHz, plus DSD64 to DSD128 over USB. It is a converter designed to be lived with for years, the kind of digital front end that finally makes tube lovers feel at home with high resolution files and streaming.

Key Features

• SuperTube Clock. PrimaLuna's boldly conceived digital clock incorporates a low noise mini-triode vacuum tube, delivering superior resolution, detail retrieval, and clarity from top to bottom while upsampling to 24 bit 192 kHz.
• Burr Brown PCM1792A. At the heart of the EVO 100 is the highly regarded TI Burr Brown PCM1792A converter, a proven chip known for its musicality and low noise performance.
• Dual Mono, Tube Rectified. Per channel dedicated tubes give each side its own signal path, while a vacuum tube rectified power supply with eleven separate regulation circuits delivers the organic sound tubes are known for.
• AC Offset Killer. Custom wound massive toroidal transformers are paired with the AC Offset Killer to lower transformer noise to a place other makers do not reach, revealing sense of space, texture, and decay.
• Point to Point Wiring. The entire signal path, including resistors and capacitors, is hand wired with heavy gauge cable by skilled craftsmen rather than routed through thin circuit board traces.
• Comprehensive Digital Inputs. USB, AES/EBU, coaxial, and optical inputs handle PCM from 16 to 24 bit at 44.1 to 192 kHz, with DSD64 to DSD128 DoP over USB and DSD64 DoP over the other digital inputs.
• Serious Build Quality. At nearly 29 pounds with premium polypropylene coupling caps, triple pi power supply filters, and custom isolation transformers separating analog and digital sections, the EVO 100 is built to last.

How the PrimaLuna EVO 100 Tube DAC Compares

PrimaLuna EVO 100 Tube DAC vs Matrix Audio ND-1 Audio DAC

The ND-1 is a fully solid state converter with a clean, precise presentation. The EVO 100 takes a very different path, using dual mono tube stages and tube rectification to add organic warmth and dimensionality that solid state designs cannot replicate.

PrimaLuna EVO 100 Tube DAC vs Luxman DA-07X USB D/A Converter

The Luxman DA-07X is a refined solid state converter with the brand's signature smoothness. The EVO 100 offers a warmer, more tube-forward character, appealing to listeners who want the texture and decay of vacuum tubes in their digital chain.

PrimaLuna EVO 100 Tube DAC vs Audiolab D9 DAC/Headphone Amp

The Audiolab D9 is a feature rich chip based DAC with a built in headphone amplifier. The EVO 100 focuses purely on converting digital to analog with a genuine tube output stage, prioritizing musicality and build over versatility.

PrimaLuna EVO 100 Tube DAC vs Accuphase DAC-60 Digital Input Board

The Accuphase DAC-60 is a digital input board designed to add DAC functionality inside compatible Accuphase components. The EVO 100 is a standalone tube converter that pairs with any system through its RCA outputs.

Frequently Asked Questions

What kind of DAC is the PrimaLuna EVO 100?

It is a vacuum tube digital to analog converter with a dual mono, tube rectified design. It combines a Burr Brown PCM1792A converter with a genuine tube analog output stage.

Which DAC chip does the EVO 100 use?

The EVO 100 uses the TI Burr Brown PCM1792A converter, a highly regarded chip known for its musicality and low noise.

What tubes does the EVO 100 use?

It uses two 12AX7 tubes, two 12AU7 tubes, and two 5AR4 rectifier tubes.

What is the SuperTube Clock?

The SuperTube Clock is PrimaLuna's tube based data clocking device. It incorporates a low noise mini-triode vacuum tube into the digital clock for improved resolution, clarity, and detail retrieval.

What digital inputs does the EVO 100 have?

It offers USB, AES/EBU, coaxial, and optical inputs, giving you flexible connection options for computers, streamers, and transports.

What outputs does the EVO 100 have?

The EVO 100 provides a stereo pair of RCA outputs to connect to your preamplifier or integrated amplifier.

What PCM resolutions does it support?

It handles PCM from 16 bit to 24 bit at sample rates from 44.1 kHz to 192 kHz.

Does the EVO 100 support DSD?

Yes. It supports DSD64 to DSD128 via DoP over USB, and DSD64 DoP over the AES/EBU, coaxial, and optical inputs.

What does dual mono topology mean here?

It means each channel has its own dedicated tubes rather than sharing a single tube buffer, which improves separation and overall musical performance.

Why is the EVO 100 tube rectified?

The vacuum tube rectified power supply uses eleven separate regulation circuits and contributes to the organic sound that sets tube designs apart from purely solid state DACs.

What is the AC Offset Killer?

The AC Offset Killer is a PrimaLuna circuit that lowers transformer noise even further than their custom toroidal transformers alone, delivering a quieter background and greater sense of space.

Why does the EVO 100 weigh so much?

At nearly 29 pounds, it uses dual potted toroidal power transformers, premium parts, and heavy point to point wiring, unlike lighter chip based DACs that often weigh ten pounds or less.

What is point to point wiring?

It means the entire signal path is hand wired with heavy gauge cable rather than routed through thin circuit board traces, preserving signal integrity from input to output.

What finishes are available?

The EVO 100 Tube DAC is available in Silver and Black finishes.

What are the dimensions of the EVO 100?

It measures 11 inches wide, 7.5 inches high, and 15.9 inches deep, and weighs 28.7 pounds.

Do I need a separate preamp or amp with the EVO 100?

Yes. The EVO 100 is a converter with RCA outputs and connects to a preamplifier or integrated amplifier, it is not designed to drive speakers directly.

Can I use the EVO 100 with a computer?

Yes. The USB digital input lets you use your computer for storage and playback with the benefits of playlists and easy access to your whole music library.

Does the EVO 100 upsample?

Yes. The SuperTube Clock upsamples to 24 bit 192 kHz for improved resolution and detail.

Can I roll tubes in the EVO 100?

Yes. Tube rolling lets you fine tune the sound to your taste. Our team at All Elite Audio can advise on suitable options for your system.
